Assume the goal is a balanced pond of healthy fish. RW under 90 this time of year are indicating to many LMB and not enough forage. Keep feeding as long as the fish will eat. Can you add 1000 5 inch BG ? Standard seine surveys are used to show yoy status and don't often show adult LMB or BG status. Catch data and visual accounts help. An electro shock survey would help but is an added cost. Remove all poor looking LMB as best you can.
